A Quick Guide to Hardware and Operating Systems
(Revised June 16th 2008)
Advice
Please call Phil Gold (416-250-6777 Ext 224) for up to the minute information or advice, since the situation changes quickly.
What's changed recently
Intel on top - Quad-Cores now dominate
The new Core family of dual-core and quad-core chips from Intel has now supplanted the earlier Pentium IV based processors across desktops, notebooks and servers. High performance has become much more affordable. For those with deep pockets, Intel offers Core 2 Extreme processors for desktops and notebooks. These run at higher speeds than the mainstream processors we normally recommend and are not listed below.
Intel is now moving from a 65 nm process to the more efficient 45 nm process and we recommend these newer chips where available.
AMD have just introduced their third generation Opteron processor and we have just tested some in house but we do not find them competitive at this time.
Processors
AXIS makes strong demands on the floating-point capabilities of your processor, so we will always advise you to buy the best floating-point performance you can afford. We recommend Quad Core processors where available so you can take advantage of AXIS Distributed processing.
1. Desktops
Intel Quad Core Chips
They are now available in the 45 nm process and represent outstanding value.
The following Chips carry our top desktop recommendation.
- Core 2 Quad Q9550 2.83 GHz 1333 MHz Bus 12 MB
- Core 2 Quad Q9450 2.66 GHz 1333 MHz Bus 12 MB
Intel Dual-Core Chips
Intel Core 2 Duo desktop chips generally run at higher speeds than the Core 2 Quad chips and are recommended if you are not using distributed processing. They are now available in the 45 nm process.
The following models are recommended:
- Core 2 Duo E8500 3.16 GHz 1333 MHz Bus 6 MB Cache
- Core 2 Duo E8400 3.00 GHz 1333 MHz Bus 6 MB Cache
AMD Chips
None recommended at this time.
2. Notebooks
Intel Dual-Core Chips
The 64-bit Core 2 Duo offers the best performance in a notebook chip and is now available at higher clock speeds. We recommend the new 45nm chips for their lower power consumption and larger cache size.
The following models are strongly recommended:
- Core 2 Duo T9500 2.60 GHz 800 MHz Bus 6 MB Cache
- Core 2 Duo T9300 2.50 GHz 800 MHz Bus 6 MB Cache
Core 2 Duo offers such strong performance that we now withdraw our recommendation for all other notebook processors.
AMD Dual-Core Chips
AMD notebook processors are not recommended at this time.
3. Workstations and Servers
Racks of dual-processor servers are a popular choice for scaling AXIS under Distributed Processing and Grid Computing. Where space is at a premium, Blade servers do an excellent job.
We no longer recommend the use of any single or dual core processors, since excellent quad core processors are now available.
Intel Xeon
For dual processor servers we strongly recommend the latest Intel Quad Core 45nm chips which offer lower power consumption and larger cache size than the 65 nm generation:
- Xeon X5482 3.20 GHz 1600 MHz Bus 12 MB Cache
- Xeon X5460 3.16 GHz 1333 MHz Bus 12 MB Cache
- Xeon E5472 3.00 GHz 1600 MHz Bus 12 MB Cache
- Xeon E5450 3.00 GHz 1333 MHz Bus 12 MB Cache
- Xeon X5472 3.00 GHz 1600 MHz Bus 12 MB Cache
- Xeon X5450 3.00 GHz 1333 MHz Bus 12 MB Cache
For quad processor servers we strongly recommend the following Intel Quad Core processor:
- Xeon X7350 2.93 GHz 1066 MHz Bus 8 MB Cache
AMD Opteron
We do not recommend Opteron processors at this time.

These tests can be quite sensitive to the types of jobs run in AXIS, and to the disk drives and memory systems in the PC. For multiple processors and cores, distributed processing is turned on using the automatic helper option.
This table should be used as a rough guide only.
I also want to draw your attention to some factors that can stand between you and good performance.
- HyperThreading . We strongly recommend that you turn off Intel HyperThreading. Windows 2000 does not support it properly, which can lead to large performance penalties. Windows 2003 and Windows XP do support it properly but it will still adversely affect AXIS run time. Intel has dropped HyperThreading from the entire range of Core 2 processors but will be reintroducing an improved version in Q3 2008.
- Real time virus checking . This can cause a massive slowdown in AXIS run times – up to four times slower. We suggest you add the directories that AXIS writes to into your exclusion list if you must run real time scanning. These directories include the directory where AXIS is installed, the SPARE directory, the Dataset Path and the location of the Import / Export database.
- Formula Tables Accelerator . To get the best performance if you are using Formula tables, remember to install the .NET Framework and turn on the Formula Tables Accelerator.
- Network bandwidth and latency . We recommend a fast network – at least 1Gbps for distributed processing or GridLink. To check whether your network is providing good performance, you can run this simple test. Run an AXIS batch recalculation, without distributed processing, on identical datasets residing in two locations – first in the same machine where AXIS is running, and then in a location across the network. If the two times vary by more than 5%, then you have a problem. Please contact GGY for details.
How much memory you need depends on how many different applications you like to run simultaneously. AXIS needs at least 384 Meg per processor core. Memory has become very inexpensive recently. More memory is better, as it will allow you to multitask more efficiently. If you are buying a new machine, or you expect to run several applications at once, it is better to buy 512 Meg per processor core or higher.
If you are running the Stochastic Processing Module you will need extra memory. We recommend at least 1 GB of memory per processor core.
Windows Vista, the latest desktop operating system from Microsoft, is very hungry for memory. We recommend 2GB of memory if you use Vista, since it needs the best part of a gigabyte of memory for itself before AXIS is even loaded.
AXIS allows you to export assumptions and projections. This can take up a lot of disk space. We suggest a minimum of 60 Gigabytes for a laptop and 120 Gigabytes for a desktop computer, not because AXIS needs this much space, but because these disks are extremely inexpensive today. The AXIS System files take up about 300 Megabytes. You can now get drives for laptops with capacities of up to 160 Gigabytes. For desktops, you can get drives of up to 500 Gigabytes each (and you can get 4 into 1 PC!).
AXIS requires a screen resolution of 1024 by 768 (XGA) or higher.
For a laptop we recommend at least a 14-inch screen and for a desktop a 17-inch LCD screen – the bigger the better.
We distribute AXIS and all updates via the Internet. If you do not have a good Internet connection we can supply AXIS on a CD. This CD can be read in any optical drive.
Operating Systems
We support and recommend Windows 2000, Windows XP, Windows 2003 Server and Windows 2008 Server. We have found them to be very stable and much easier to manage than previous versions of Windows. We also support the new Windows Vista operating system, but we are not recommending Vista at this time.
AXIS new releases no longer support Windows 95, Windows 98, Windows ME or Windows NT. Although older versions of AXIS will run on these operating systems we can no longer fully support those operating systems because Microsoft no longer produces service packs to fix the bugs in them. Sometimes the bugs in those older operating systems can affect AXIS, and Microsoft will not assist us, or you, to resolve them, as they do for the newer operating systems. Sometimes we can help you without Microsoft’s help, but in other cases we cannot find a work around and now you know why.
We strongly recommend users to have an Internet and e-mail connection since we provide a lot of support and updates over the Internet from our web site www.ggy.com.Information for IT Professionals

Recommended Hardware for a GridLink Farm
You may be considering a 16 core farm or a 128 core farm, or something in between. We strongly recommend you to consider your future needs before setting up even a small farm, so that you can continue to use the hardware you choose now as part of the larger farm you may need tomorrow. Please review this word document for further information on hardware requirements:
